Superposition of Multiplicative Multifractal Traffic Streams

چکیده
Source traffic streams as well as aggregated traffic flows often exhibit long-range-dependent (LRD) properties. In this paper, we model each traffic stream component through the multiplicative multifractal counting process traffic model. We prove that the superposition of a finite number of multiplicative multifractal traffic streams results in another multifractal stream. This property makes the multifractal traffic model a versatile tool in modeling traffic streams in computer communication networks. There, a node is loaded by a traffic flow resulting from the superposition of source streams and aggregated LRD (and other) streams. The structure and the burstiness of the superimposed process is studied, and useful mathematical relations are obtained.

Multiplicative Multifractal Modeling of Long-range-dependent (lrd) Traac in Computer Communications Networks
Source traac streams as well as aggregated traac ows often exhibit long-range-dependent (LRD) properties. In this work, we model traac streams using multi-plicative multifractal processes. We develop two type of models, the multifractal point processes and multifractal counting processes. We demonstrate our model to eeectively track the behavior exhibited by the system driven by the actual traf...

متن کاملA Performance Comparison of Monofractal and Multifractal Traffic Streams
This paper focuses on the differences between monofractal and multifractal network traffic, both in terms of modeling approaches, and in terms of practical impacts on network performance. Empirical traffic traces are used in the parameterization and evaluation of traffic models. Simulation is used to evaluate the performance differences between monofractal and multifractal traffic, both for ind...
متن کاملInternet traffic classification using multifractal analysis approach
In this work, we present a traffic classifier based on the theory of multifractal network traffic. We use precisely the concept of multiplicative binomial cascades to get a feature vector to be used in the classification scheme. This vector is obtained by the multiplier variances of the multiplicative cascade traffic view. We analyze the performance of the technique proposed by a popular ML S...
متن کاملCapturing the complete multifractal characteristics of network traffic
We propose a new multifractal traffic model for network traffic. The model is a combination of a multiplicative cascade with an independent lognormal process. We show that the model has all the important properties observed in data traffic including LRD, multifractality and lognormality. We also demonstrate that the model is flexible enough to capture the complete multifractal characteristics o...
